316LVM surgical steel and metal alloy Austrian crystal Channel-set N/A Nipple Each piece is sold individually. The Paved Crystal Nipple Clicker is a high-quality piece. The design best suits nipple piercings. Put this clicker through your piercing from the front and snap it closed. This clicker is a great alternative to like captive bead rings or circular barbells. If you've worn a hinged segment ring before, these are very similar. 316LVM surgical steel goes through a process called low carbon vacuum melting. The process sucks the nickel out of the steel. Nickel is one of the most common causes of metal allergies. This process cannot remove 100% of nickel. As a result, a small number of people react to it. We recommend our anodized, blackline, or untreated titanium body jewelry if this is a concern for you. Otherwise, 316LVM surgical steel is an excellent option for people with metal allergies. The yellow and rose gold options are PVD. PVD is more durable and therefore lasts longer than traditional plating. However, the plating may irritate metal allergies. The charm is a metal alloy, which is ideal for casting and makes them perfect for jewelry with fine details. Many people have sensitivities to these alloys and may react. Metal Alloys with a PVD coating can help negate this reaction, but they may still irritate those with the strongest sensitivities. To avoid turning green, metal alloy jewelry is recommended to be cleaned often and not worn in moist/sweaty places. The stones are Austrian crystals. We love Austrian crystals because, with proper care and cleaning, they never lose their sparkle like other similar stones. Show us where you wear yours with #BodyModsFamous on Instagram.
